Problems solved by technology
[0004] In view of the shortcomings of the existing methods, this application proposes an item recommendation method, device, electronic equipment, and medium based on knowledge graphs to solve the problem that the existing recommendation methods are prone to performance degradation due to too sparse user behavior matrix or due to neglect of users. Behavior that leads to technical problems with low accuracy of the algorithm

The invention provides an article recommendation method and device based on a knowledge graph, electronic equipment and a medium. The method comprises the following steps: determining a semantic-based first similarity between any two articles according to a knowledge graph of a plurality of articles; according to the user score of each article, determining a second similarity between any two articles based on the user behavior; according to the first similarity and the second similarity between the non-behaved articles of each user and the behaved articles and the user score of the behaved articles of each user, determining a predicted score of each user on the non-behaved articles; According to the predicted score of each user on the items which do not generate the behaviors, determining a recommendation list of the items which do not generate the behaviors for each user, and pushing the recommendation list to a terminal of the corresponding user. The article with a high prediction score can be recommended to the user as an article conforming to user preferences, habits and personalized requirements, and the user is helped to make a decision quickly.
Description
technical field [0001] The present application relates to the technical field of item recommendation, and in particular, the present application relates to a method, device, electronic device, and medium for item recommendation based on knowledge graphs. Background technique [0002] The recommendation system can predict the user's preference for the product according to the user's preferences, habits, individual needs and product characteristics without the need for the user to explicitly provide the content they want, and recommend the most suitable product for the user. [0003] Existing recommendation systems usually adopt collaborative filtering or content-based recommendation. The collaborative filtering method is prone to performance degradation due to the user behavior matrix being too sparse, and there is a cold start problem that cannot recommend new items; the content-based recommendation method pays attention to the content information of the item itself and igno...
